Please be informed that the guest would like to amend the staying period from 14-15 Feb 2016 to 14-15 Dec 2015 due to wrongly booked. We found the room rate for Dec 2015 is higher, kindly advise if hotel would allow to amend the dates to Dec with same rate? Also, guest would like to amend the occupancy from 4 adults to 8 adults (total 2 adults each room). Guest also would like to have 2x King bed rooms and 2x Twin bed rooms. Please advise. Thank you.
